MS Word-like program in Spanish?

[Seiken]

My wife has this job where one of the requirements is to create guidelines, etc in spanish. Her spanish grammar isn't the best and she asked me if there was some program out there like MS Word that would spell check the spanish words and stuff.

Microsoft's Word (Spain edition?)
No really.. I have no clue. Any ideas?

EDIT: Nevermind. I just changed the Dictionary language in Word.
